"Most of this island has been English speaking for a 1000 years." What's that got to do with it, saxonach? Nobody calls them the English Isles.

For what it's worth anyway, "British" refers to the people who were in England before the English arrived, which is why the Romans used the term.

So changing the name to "Celtic" from "British" wouldn't make much difference. The name is Celtic either way - whatever that means.

The neatest alternative name I've seen is the acronym "The WISE Isles" - from the names of the main parts. (That misses out the Isle Of Man and the Cornish of course.) Or maybe "The Isles of Man", from the natural capital of the archipelago, situated right in the middle.

But I can't see either of them catching on.
